Safety and Efficacy of Dapagliflozin in Recurrent Ascites: A Pilot Study.

BACKGROUND

In cirrhosis, activation of renin-angiotensin-aldosterone system leads to sodium and water retention causing ascites. Dapagliflozin, a sodium glucose linked transporter-2 inhibitor, induces natriuresis in patients with heart failure. A similar natriuretic effect may improve ascites in patients with cirrhosis. In this pilot study, we evaluated the safety and efficacy of dapagliflozin in patients with cirrhosis and recurrent ascites.

METHODS

Forty patients with recurrent ascites and cirrhosis were randomized to 1:1 in a double blinded fashion to receive either dapagliflozin (10 mg/day) with standard medical therapy (Group A) or placebo with standard medical therapy (Group B). The primary outcome was control of ascites at 6 months. Secondary outcomes were urine output, 24-h urinary sodium, Child Turcotte Pugh (CTP), model for end-stage liver disease (MELD) scores, survival at 6 months, incidence of acute kidney injury (AKI) and infections.

RESULTS

The 2 groups were comparable at baseline. Control of ascites at 6 months was significantly better in group A than that in Group B (p = 0.04). Change in urinary sodium was significantly higher in Group A (p < 0.001]. However, there was no difference in change in urine output, CTP or MELD scores and survival (65% vs 72.2%, p = 0.75) between the groups at 6 months. Incidence of AKI (50% vs 15%, p = 0.04) and infections (55% vs 20%, p = 0.04) were significantly higher in Group A.

CONCLUSION

Significantly better control of ascites and higher natriuresis are observed with dapagliflozin. However, it does not improve disease severity scores or survival, and is associated with increased AKI and infections (NCT05014594).
